Using this belt bag is super easy. First, adjust the nylon strap to your desired length using the snap - in buckle closure. Then, zip up the top closure to secure your items. You can use the long mesh and smaller mesh interior pockets to organize things like your phone, keys, or cards. The back zip pocket is great for storing items you want quick access to. When it comes to maintenance, simply wipe the bag with a damp cloth if it gets dirty. Avoid using harsh chemicals as they may damage the polyester blend material. Keep it away from sharp objects to prevent tears. Also, store it in a cool, dry place when not in use to maintain its shape and quality.
